Definitions
- the invention relates to a method and a system for controlling vehicle speed in a vehicle equipped with brake cruise control when the vehicle is travelling downhill.
- the invention can be applied in heavy-duty vehicles, such as trucks, buses and construction equipment. Although the invention will be described with respect to a heavy-duty vehicle, the invention is not restricted to this particular vehicle, but may also be used in other vehicles such as articulated haulers, wheel loaders, and other working machines or automobiles.
- Driver assistance systems for automatically controlling the speed of a vehicle allow a driver to specify a selectable driving speed via actuating means.
- the set speed is then maintained independently of the operation of an accelerator pedal of the vehicle.
- the speed can be set by the driver and can also be retained independently of the driving situation, such as uphill or downhill driving.
- the vehicle will then use suitable means such as auxiliary brakes or service brakes to maintain the set speed.
- WO 2008/094111 A1 relates to a cruise control system for a motor vehicle and a method for controlling the target speed thereof.
- the cruise control system is adapted to control the engine so as to endeavour to keep the vehicle speed essentially equal to the target speed, and to control one or several brakes of the vehicle so as to endeavour to restrict the speed of the vehicle to a brake reference speed.
- the target speed is automatically and temporarily increased from a basic value to a modified value corresponding to a speed lower than the brake reference speed when it is established that the following conditions are fulfilled: the system has been actuated to control a braking operation by ordering a braking power for said brakes, and the braking power ordered during the present braking operation has dropped below a given threshold value.
- US 2004/195022 A1 relates to a drive control apparatus for a vehicle having an accelerator pedal and a brake pedal both of which are operable by a driver of the vehicle, and a power source.
- the drive control apparatus includes a vehicle speed measuring device which measures a vehicle speed, a control operation switching device which places the drive control apparatus in an operating state upon receiving an operation from the driver, a vehicle speed adjusting device which is placed in an operating state upon receiving a command from the control operation switching device, and which, during the operating state, automatically adjusts the vehicle speed measured by the vehicle speed measuring device, independently from driver's operations of the accelerator pedal and of the brake pedal, so that a target vehicle speed is achieved, and a target vehicle speed changing device which changes the target vehicle speed depending on predetermined driver's operations of the accelerator pedal or of the brake pedal.
- DE 10 2006 05 179 A1 relates to a method for automatic downward velocity control, commonly known as brake cruise control, which is capable of absorbing energy induced by the inclination automatically. In this way the driver must no longer be active to maintain a substantially constant traveling speed.
- the downward velocity control is triggered when the accelerator pedal is released, and the vehicle begins to accelerate downhill.
- the vehicle speed is controlled towards target vehicle speed, which is a desired predetermined constant vehicle speed set by the driver.
- the object of the invention is to provide a method and a system for controlling vehicle speed in a vehicle equipped with brake cruise control which eliminates the above problems.
- the invention allows automatic control of the speed of a vehicle requiring a minimum of intervention and providing a high level of comfort for the driver.
- An object of the invention is to provide a method and a system for controlling vehicle speed in a vehicle equipped with brake cruise control.
- the object is achieved by a method and a system according to the appended claims.
- service brake is used to denote the normal, or main brakes used in heavy-duty vehicles, usually operated by the driver depressing a service brake pedal.
- the service brakes are often, but not necessarily, air brakes operated by compressed air controlling friction brakes provided on each wheel to be braked on the vehicle.
- auxiliary brakes is used to denote additional means for assisting braking of the vehicle. Auxiliary brakes are used in addition to the service brakes and allow for prolonged brake application without requiring assistance from the service brakes. In this way, wear and unnecessary heating of the service brakes can be avoided.
- Such auxiliary brakes can comprise an exhaust valve, for activating an exhaust brake, engine brake valves, for activating a compression release engine brake, a fluid retarder, for generating a braking force on a propeller shaft, or means for driving a compressor or generator to generate a braking force.
- the auxiliary brake can comprise a generator, a motor-generator or other suitable means.
- the object is achieved by a method according to the appended method claims.
- the invention relates to a method for controlling vehicle speed in a vehicle equipped with brake cruise control when the vehicle is travelling downhill.
- the method comprises the steps of;
- the steps of detecting a current vehicle speed and automatically applying a brake torque using at least an auxiliary brake to maintain the first brake set speed are actions performed by the brake cruise control without input from the driver.
- control unit provided in the vehicle detects manual application of the service brake, i.e the driver is applying the service brake, then the control unit is automatically arranged to perform the steps of:
- control unit is automatically arranged to set the second brake set speed at a level where the second brake set speed can be maintained by the auxiliary brake.
- the method is arranged to repeat the above steps until it is detected that the downhill condition has ended, i.e. the slope is levelling out and normal cruise control can be resumed.
- the brake set speed is set to a third brake set speed that is lower than the second brake set speed.
- this step can be performed automatically in response to one or more signals transmitted to the control unit by an inclination sensor, an accelerometer, an on-board topographic database, a GPS-receiver, or a similar suitable device.
- the brake set speed is restored to the first brake set speed when the driver issues a resume command.
- a resume command can involve the driver actuating an accelerator means or a resume switch on the dashboard, or on or adjacent the steering wheel.
- the resume command is detected by the control unit, which restores the first brake set speed
- the invention relates to a vehicle speed control system in a vehicle equipped with brake cruise control when the vehicle is travelling downhill.
- the system comprises a sensor arranged to detect a current vehicle speed; a service brake; at least one auxiliary brake; and a control unit having a user selectable input for receiving a brake set speed, said control unit being arranged to compare the current vehicle speed with a first brake set speed and control the auxiliary brakes to maintain the first brake set speed.
- the first brake set speed can be set once by the driver and is then stored in the control unit for future use.
- the system can prompt the driver for an input, e.g.
- the speed sensor can be a separate sensor provided for this purpose, a sensor forming part of an ABS arrangement in the service brake, or a virtual sensor where the vehicle speed is calculated from suitable engine and transmission parameters.
- the control unit is arranged to detect if the service brake is applied to retard the vehicle speed. When a manual application of the service brakes is detected, the control unit is automatically arranged to set the brake set speed to a second brake set speed that is lower than the first brake set speed. The control unit is subsequently arranged to apply a brake torque using at least the auxiliary brake if the current vehicle speed exceeds the second brake set speed.
- the auxiliary brake is used as the primary source of brake torque. Only when the auxiliary brake or brakes cannot maintain the second brake set speed will the service brake be actuated by the control unit. Automatic actuation of the service brakes should only be performed during short periods of time of intermittently; the driver may be notified if prolonged automatic application of the service brakes is carried out.
- control unit is arranged to set the second brake set speed at a level where the brake set speed can be maintained by the auxiliary brake or brakes.
- the brake cruise control brake set speed is restored to the first brake set speed.
- the control unit is arranged to restore the brake set speed to the first brake set speed when the control unit has detected that the downhill condition has ended.
- the control unit is arranged to perform this action in response to one or more signals transmitted to the control unit by an inclination sensor, an accelerometer, an on-board topographic database, a GPS-receiver, or a similar suitable device.
- control unit is arranged to restore the brake set speed to the first brake set speed when the driver issues a resume command.
- a resume command can involve the driver actuating an accelerator means or a resume switch on the dashboard, or on or adjacent the steering wheel.
- the object is achieved by a computer program comprising program code means for performing the above-mentioned method steps for controlling vehicle speed in a vehicle equipped with brake cruise control when said program is run on a computer.
- the invention further relates to a computer readable medium carrying a computer program comprising program code means for performing the above-mentioned method steps for controlling vehicle speed in a vehicle equipped with brake cruise control when said program product is run on a computer.
- the advantage is that the driver can be relieved of a number of the manual actions by transferring control of the brake cruise control system to a control unit.
- the brake cruise control system active, the driver merely needs to apply the service brakes to indicate that a speed reduction is desired.
- the control unit will automatically set the brake set speed to a lower value. This lower value is retained to the end of the downhill road section, or until the driver indicates a further speed reduction.
- the control unit can be arranged to automatically reset the brake set speed to the initial brake set speed.
- the driver can indicate that the initial brake set speed is to be reset by issuing a resume command, for instance by actuating a resume switch or by depressing an accelerator pedal.
- a resume command for instance by actuating a resume switch or by depressing an accelerator pedal.

- Figure 1 shows a rear driven axle 123 and a trailing axle 125 with associated wheels 124, 126, as well as a steerable axle 127 with associated wheels 128.
- Each axle 123, 125, 127 supports corresponding wheels 124, 126, 128 having service brake components 131, 132, 133 which can be manually or automatically actuated depending upon the particular application and operating conditions.
- a vehicle equipped with an anti-lock braking system can assume automatic control of braking under appropriate conditions such as when the vehicle is braking and the system detects a sufficient slip differential among one or more wheels, or when the vehicle travels downhill under the control of a cruise control system.
- the service brake components 131, 132, 133 include wheel speed sensors and electronically controlled pressure valves (not shown) to effect control of the vehicle braking system.
- the service brake components 131, 132, 133 are connected to a central electronic control unit (ECU) 140 by means of suitable wiring, as schematically indicated by the input 134 and output 135 in the figure.
- a wheel speed sensor 136 is schematically indicated in Figure 1 . The output signal from one or more such sensors can be used for calculating the vehicle speed.
- the vehicle 100 includes conventional operator controls such as an accelerator pedal 141, a brake pedal 142 and an optional clutch pedal 143 (for manual transmissions), as well as an operator interface, such as dashboard control console (not shown).
- the dashboard control console can include any one of a number of output devices, such as lights, displays, buzzers, gages, and the like, and various input devices, such as switches, push buttons, potentiometers, or the like. Examples of input devices can be controllers 144, 145 for setting and/or restoring a brake cruise control set speed in in a brake cruise control system.
- the controller 144 for setting the brake cruise control set speed and the controller 145 for restoring the brake cruise control set speed are both connected to the ECU 140.
- the vehicle control system includes the central ECU 140 which is connected to electronic control modules 146, 147 for the engine 110 and the transmission 120, respectively.

- Sensors may include a steering angle sensor, wheel speed sensors (included in service brake components 131, 132, 133), an electronic accelerator pedal sensor, a brake pedal sensor or switch, a clutch control/sensor, an output speed sensor, a sensor/accelerometer 151 for indicating vehicle inclination, at least longitudinal inclination, and sensors for various engine parameters 152.
- the ECU 140 monitors information from the sensors and evaluates their input to determine parameters such as current engine speed and torque, brake pedal position, accelerator position, road speed, cruise control status, and cruise control brake set speed, cruise control switches, clutch pedal position, among many others.
- the control unit detects that the downhill condition has ended.
- the ECU is then arranged to restore the brake cruise control brake set speed to the first brake set speed v B1 wherein the vehicle speed is increased to the first brake set speed v B1 by the cruise control system over a fourth road section X 4 .
- the control unit is arranged to perform this action in response to one or more signals transmitted to the control unit by an inclination sensor, an accelerometer, an on-board topographic database, a GPS-receiver, or a similar suitable device.
- One or more of these signals in combination with a detected absence of auxiliary brake actuation, can be used to detect that the downhill condition has ended.
- FIG. 3A shows a schematic flow chart for performing the method according to the invention in a vehicle equipped with a brake cruise control system.
- the process is started in a first step 311, where after a first brake set speed is set by the driver in a second step 312.
- a downhill condition is detected, causing the brake cruise control system to control the vehicle speed in order to maintain the first brake set speed in a fourth step 314.
- a number of parameters such as the vehicle speed and road gradient are monitored and at least the auxiliary brakes are applied if the speed exceeds the first brake set speed. If no downhill condition is detected in the third step 313 then the process is ended in a final step 317.
- step 315 an additional check is performed in a fifth step 315 to detect if the service brakes have been manually actuated or not. If the service brakes have not been actuated by the driver, then the process returns to the third step 313 to determine if the downhill condition continues. The process then proceeds to the fourth step 314 to continue performing brake cruise control for maintaining the first brake set speed. On the other hand, if the service brakes have been actuated by the driver, then the process continues to sixth step 316, where the brake set speed to a second brake set speed that is lower than the first brake set speed.
- the second brake set speed is set automatically by the brake cruise control system and can be selected from a stored table or matrix, and/or depending on parameters such as the current road gradient.
- the second brake set speed can be set to the speed detected when the driver releases the service brakes.
- the process then returns to the third step 313 to check if a downhill condition exists. If this is the case then it proceeds to the fourth step 314 to continue performing brake cruise control to maintain the lower second brake set speed.
- the brake cruise control system can be required to perform a downshift and/or additional actions to reduce the vehicle speed to the new set brake speed. The process then resumes as described above.
- the process as described above is continued as long as a downhill condition is detected in the third step 313.
- the brake cruise control system detects that the downhill condition has ended, then the process leaves the control loop and proceeds from the third step 313 to a final step 317.
- the end of a downhill condition is preferably detected automatically by the brake cruise control system, e.g. by monitoring the road gradient. Alternatively, the end of a downhill condition is detected when the driver actuates the accelerator or a switch provided for this purpose.
- the process is ended in the final step 317 and reverts to regularly monitoring the detected parameters, only to be resumed if a subsequent downhill condition is detected. If the brake set speed has been changed during a previous downhill section then it is automatically reset to the first set brake speed prior to a subsequent downhill section.
- the process as described above is continued as long as a downhill condition is detected in the third step 323.
- the brake cruise control system detects that the downhill condition has ended, then the process leaves the control loop and proceeds from the third step 323 to a seventh step 327.
- the end of a downhill condition is preferably detected automatically by the brake cruise control system, e.g. by monitoring the road gradient. Alternatively, the end of a downhill condition is detected when the driver actuates the accelerator or a switch provided for this purpose.
- the seventh step 327 it is determined if the set brake speed has been changed or not. If the set brake speed has not been changed then no action is required, and if the brake set speed has been changed then it is reset to the first set brake speed.
- the process is ended in a final step 328 and reverts to monitoring the detected parameters, only to be resumed if a subsequent downhill condition is detected. If the brake set speed has been changed during a previous downhill section then it is automatically reset to the first set brake speed prior to a subsequent downhill section.
